Lockheed Martin has signed a memorandum of understanding with Spaceport America in New Mexico. Lockheed wants to perform tests at the spaceport site.
Not sure if this is related to Lockheed's agreement with Bigelow Aerospace to ferry people to Bigelow's space station. But it does show one more people of evidence that either LM is evolving or they finally see money in the private space industry.
From What The Bigelow/Lockheed Agreement Says about Lockheed:
Lockheed builds rockets for the military and NASA because it is a safe way to make money. What the new agreement with Bigelow shows me is that Lockheed Martin sees these stations as a viable way to make money. They don't normally push new ideas because they are risky. Risky ventures are for companies trying to make a profit from nothing, like SpaceX or Bigelow. I think it is a wonderful milestone in new space that a traditional "dinosaur" is willing to throw their hat into a private space venture, expecting to make money.
